L_INT pEXT_CALLBACK YourFunction(hCellWnd, nSubCellIndex, nX, nY, pBitmap, szPixelValue, pUserData)
A handle to the window that represents the Medical Viewer Cell.
A zero-based index of the sub-cell where the probe tool is displayed.
A Value that represents the X position of the cursor.
A Value that represents the Y position of the cursor.
Pointer to a bitmap handle that is set in the specific sub-cell.
A string that contain probe tool text. the user can update this text to display on the probe tool instead.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_DispContainerSetProbeToolUpdatedCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
